MonoSS Coilover Kit

Its construction features a robust monotube damper housed within a 52mm carbon seamless steel tube, incorporating a high-performance internal piston engineered for optimal damper response. Complementing the damper are cold-bent springs crafted from high-strength SAE9252 steel, meticulously chosen to strike a balance between spirited driving dynamics and everyday comfort. The integration of Japanese KOYO 6204Z bearing pillow ball mounts in the top hats (where applicable) promotes smooth suspension articulation. The bottom shock brackets are constructed from T7075 forged aluminum or carbon steel, offering a lightweight yet durable foundation that often includes provisions for brake lines. Key features include 16 levels of adjustable damping, allowing drivers to fine-tune their suspension to meet varying road conditions and driving preferences. The spring rates are set at 6kg/mm for the front and 5kg/mm for the rear, with corresponding spring lengths of 180mm (front) and 170mm (rear), and inner diameters of 62mm for both. The system allows for independent spring tension and height adjustment, offering comprehensive control over ride height and pre-load. Installation by experienced professionals is highly recommended for this kit. The MonoSS coilover kit is specifically designed for the Toyota Corolla E120 and E130 models from 2003 to 2008.
